DRIVE-CHAIN LINK.

QPECIFICATIQN -orming part of Letters Patent No. 316,992, dated May 5,1885. Application filed February 6, 1885. (ModeL) To all whom it mayconcern:

Be it known that I, EDWARD Y. MooRE, residing at Evanston, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Drive-Chain Links, of which the following, in connectionwith the accompanying drawings, is aspecification.

In the drawings, Figure 1 is a face or top View of two of my improvedlinks connected together. Fig. 2 is a vertical section of the links,taken on the line 00 wof Fig. 1. Fig. 3 isa face or top View of thelinks detached; and Fig. 4 is aside view of two of the links, showingthe position in which they may be connected together.

. My invention relates to that class of drivechain linksin which thelinks are attachable together or detachable by hand when held' in acertain position; and the obj ect of my invention is to provide a neatand strong link of small cost and-easy to manufacture, all of which Iwill hereinafter describe.

Like letters of reference indicate like parts.

A A are drive-chain links. These links may be made either of cast ormalleable metal, and each consists of two side bars, B B, and of two endbars, 0 and G. The end bar 0 is continnone and extends from one side barto the other, as shown.

a a are disk-like extensions projecting in the longitudinal direction ofthe side bars from those corners of the link which the bar 0 connects,and a a are studs or comparatively short cylindrical parts extendingfrom the inner faces of the disks or extensions a a.

D is a tongue extending from the bar 0, and having a depression orsocket, b, and projecting out between but not uniting the parts a a. Thebar 0 is adapted to enter the hook or socketed tongue D.

E E are hook-like or socketed extensions formed on the bar 0, or atits junction with the side bars. The sockets or depressions b b in the partsE E are curvilineal in the same direction as the hook D is, as shown. Byhaving at each end of the link the sockets or hooks similarly curved andin the form of about half a circle or less than half a circle upward ordownward, as may be deemed most desirable, I am enabled to cast the linkin a comparatively easymanner.

The inner ends of the hooks E E are reenforced or strengthened by websor flanges c c, which are continuous with the end bar 0.

The outer rims of the hooks E E are not flush with the outsi-des of thebars 13 B, room being thus provided, as shown at (Z (Z, to receive theextensions aa when the links are arranged together, as shown, so thatthe said extensions will then be flush with the outer lines of thechain; but these recesses (I dare not absolutely necessary. I also gainor cut the recesses d d with a slope, e, as shown in Fig. 3. Having therecesses so sloped allows the links to be brought together or formedinto asmall angleabout thirty-five or forty degrees-for the p urpose ofputting them together or taking them apart.

To use or put together the links A A,they are placed in the positionshown in Fig. 4, when the bar 0 on one link may be placed in hook D onthe other. The studs a a will also at the same time slip into the hooksE E, and by turning the upper link so as to be in a horizontal line withthe other one they will be securely connected. With more links andsuccessive operations of thesaine kindacontinuous chain may be formed.To undo them, one link is turned over so as to form an angle of aboutthirty to forty degrees with lower one, and then lifted upward, whenthey will come apart.

It will be seen that when two of my links i are placed together the endbar 0 on one link and the studs a a on the other form the journal orpivotal joint or connection between the links, while the hook D on oneand the hooks E E on the other form the central bearings for pivotalaction. It will also be seen that two of the links cannot be partedlaterally or sidewise, that their construction is simple, and that theyform together a very neat and strong drivechain.

A very important feature of my invention is,

that the hooks or sockets are all formed in.
